Abstract

The invention provides a padlock with a quickly changeable shackle, comprising a locking core, a locking member, blocking balls, a lock body on which two limb receiving chambers and a passage are disposed, and a shackle which takes U-shape defined by a longer and a shorter parallel limbs respectively received in the limb receiving chambers to lock the padlock. A ring groove with an abutment head is disposed at the free end of the longer limb, and a depressed portion with a screw hole is provided on the circumferential surface of the abutment head. A shackle changing screw is threaded into the screw hole and the end face of the screw in the threaded position is higher than the depressed portion and lower than the circumferential surface of the abutment head. The invention further provides a padlock having a freely-convertible deadlock mechanism.

Claims (5)

1. A padlock with a quickly changeable shackle comprising:
a lock body, within which a locking core, a locking member coupled to the locking core, and blocking balls are provided, and on which a deeper limb receiving chamber, a shallower limb receiving chamber and a passage in communication with the deeper limb receiving chamber are disposed; and a shackle, which takes U-shape defined by a longer parallel limb received in the deeper limb receiving chamber and a shorter parallel limb received in the shallower limb receiving chamber, wherein each of said two limbs is provided with a latching recess matched with the blocking ball, a ring groove with an abutment head is disposed at the free end of the longer limb, and wherein the longer limb is allowed to be turned and elevated in the deeper limb receiving chamber and the shorter limb is allowed to be elevated in and dropped out of the shallower limb receiving chamber when the padlock is in an unlocked status, and the latching recesses on the longer and shorter limbs are respectively engaged with the blocking balls when the padlock is in a locked status;
characterized in that a depressed portion is provided on the circumferential surface of the abutment head of the longer limb, on which there is a screw hole perpendicular to the depressed portion; a shackle changing screw is threaded into the screw hole and the end face of the screw in the threaded position is higher than the depressed portion and lower than the circumferential surface of the abutment head; the shackle changing screw is formed to have a shape and dimensions that allow the screw to pass through the passage on the lock body;
and the screw hole is positioned such that the screw hole and the passage are in the same horizontal plane and reciprocally staggered when the padlock is in the unlocked status.
2. The padlock as claimed in claim 1, characterized in that the passage is arranged in a position on the lock body where the lock body is aligned with a longitudinal central axis of the deeper limb receiving chamber.
3. The padlock as claimed in claim 1 or 2, characterized in that the passage is staggered with respect to the screw hole at an angle of 180° when the padlock is in the unlocked status.
4. The padlock as claimed in claim 1 or 2, characterized in that the passage is staggered with respect to the screw hole at an angle of 90° when the padlock is in the unlocked status.
